Description
Trichloroacetic acid is a strong organic acid offered at min. 99 % purity in p.a. grade for analytical and laboratory applications. It is registered under CAS number 76-03-9 and EG number 200-927-2, with empirical formula CCl₃COOH and a molar mass of 163,40 g/mol. Density is 1,62 g/cm³, the boiling point is 197 °C and the flash point exceeds 110 °C. The p.a. specification suits quantitative work and reference procedures that demand consistent acid strength. Laboratories benefit from the defined molar mass, density and thermal profile when calculating concentrations, planning dilutions and documenting methods. The kilogram glass format provides economical stock for routine analytical series while maintaining the integrity expected of a pro analysi grade trichloroacetic acid.
This article is part of Analytical grade solvents (p.a.), in Solvents.

Questions about Trichloroacetic acid, min. 99 %, p.a., 1 kg, glass
What is this article?
Trichloroacetic acid, min. 99 %, p.a., 1 kg, glass is the article on this page. Luminix Health distributes Carl Roth for laboratory use. It sits in Analytical grade solvents (p.a.), inside Solvents, in Lab chemicals.
An analytical-grade solvent, often marked p.a., has impurity limits tight enough for classical analysis and for preparing reagents. It is not automatically low enough in UV absorbance for HPLC, and it is not dry enough for a water-sensitive reaction. The grade is the purchase.
A solvent dissolves. The grade says which impurities are low enough for the method. Analytical grade is the ordinary pure solvent. HPLC and LC-MS grades limit the absorbance and the ions that would become peaks or background. A dry solvent has had water removed. A deuterated solvent is for NMR, where the hydrogen signal would otherwise drown the sample. Technical grade is for cleaning and for synthesis that does not need a chromatogram. Identity is on PubChem. Names follow IUPAC. Hazards follow ECHA, the CLP Regulation and REACH.
Which category should I open next?
The category is Solvents. The sub-category is Analytical grade solvents (p.a.). The catalogue is Lab chemicals.
Shelves beside this one are HPLC & LC-MS grade solvents, Dry & deuterated solvents (NMR, synthesis), Technical & synthesis grade solvents and Green & alternative solvents.
What should I check before I order?
When this page shows a safety data sheet, use that manufacturer file. Hazard text does not belong in the sales description. For a pack size, a grade or a certificate that is not on the page, send a quote request or contact the team.
